Ranking Methodology

Our team used the following criteria to assess the best San Diego solar companies.

  • Feedback and reviews from customers: Most San Diego solar installers have both positive and critical reviews. However, a good review ratio indicates a company's reliability and responsiveness to issues.

  • Panel brands and quality: The best solar companies stay up-to-date with new technology, offering equipment from innovative, dependable manufacturers.
  • Educational approach: Solar technicians must be knowledgeable. They should use their years of experience address your questions on how to maintain your system and maximize its performance.
  • Warranty and service offerings: Solar companies should stand behind their equipment and services with warranties. We evaluated how each contractor responds to issues and warranty claims, focusing on promptness and customer satisfaction.

Benefits of Solar Energy

Solar energy provides multiple benefits. Let's look at a few of them.

  • Lowered energy bills: With solar panels, you create power without paying the tacked-on costs of grid-connected power. You can eliminate your bills completely if you go off-grid. Plus, a significant number of states have adopted net metering, which permit you to earn money by selling your unused energy back to the grid.
  • Reduced carbon footprint: The sun is the universe's most abundant clean energy source, meaning you can reduce or eliminate your home's dependence on non-renewable sources.
  • Better energy independence: Solar panel systems with energy storage systems work through blackouts and emergencies, and you won't have to depend on the grid for your safety and well-being.

What Solar Incentives Are Available to San Diego Homeowners?

California homeowners who go solar could qualify for reimbursements, tax credits, rebates and special financing. Here are just a few of the local incentive offerings.

Incentive Amount:

100% of system value; 75% of system value exemption for dual-use equipment

How To Choose the Best Solar Company in San Diego

Choosing a company is the first step toward an effective and valuable solar system. Consider each of these criteria in your contractor search.

Licensing and Training

California requires solar companies to hold licenses for each type of equipment they install, which can include solar photovoltaic (PV) systems, water heaters, boilers, HVAC, and pool heaters. Contractors must take a highly comprehensive educational series, gain four years of field experience, and pass written exams to earn licensure. Look for private accreditations from the North American Board of Certified Energy Practitioners (NABCEP), among the solar industry's most trusted trade groups. Its program includes certifications for both solar photovoltaic and water heating installers.

Cost of Solar Panels in San Diego

Your solar modules' model will affect how much power you can generate. Monocrystalline panels are among the highest quality and perform the best but cost the most. Polycrystalline panels offer you a budget panel with a traditional design, but at the cost of less power generation. Thin-film panels have a low cost and are excellent for non-traditional roofs, but aren't recommended for large home installations.

You can also add electric car (EV) chargers and battery backup systems. These will increase your total installation cost, but they can increase your solar system's efficiency. Not every solar company offers these add-ons, so look for a contractor that installs them if it's crucial for you.

A majority of San Diego homeowners select solar systems sized for five kilowatts (kW) of electrical capacity. These systems run about $17,350 to install, considering both parts and installation. You can find more specific solar cost information in the table.

Solar Panel CostAverage Cost
Solar Monocrystalline$1,226
Solar Polycrystalline$956
Thin-Film$559
Solar Battery$784
Solar Home EV Charger$2,942

Financing Solar Energy in San Diego

Choosing the ideal financing solution will impact your overall solar system cost and potential savings. Common payment options include cash payments, power purchase agreements, loans, and leases. Though it involves a large up-front payment, cash is the most affordable choice because it doesn't accrue interest and qualifies you for incentives. Solar loans are the next best option. As with a car loan or mortgage, you'll pay a monthly rate towards system ownership, including interest. You can still apply for money-saving solar incentives, and depending on your lender, you could put as little as $0 down. Solar leases let you use your panels for a set monthly rate, while PPAs let you pay just for the energy you use, similar to an electric bill. Both options disqualify you for solar incentives and do not provide you system ownership. Solar experts generally don't recommend them, but they might be suitable in some cases. Ask each business you're evaluating about the payment plans it offers. A team member can help you determine the most suitable option for your budget.

The table below lists the average payback periods for different capacities of solar systems in San Diego.

You are eligible for a 26% federal solar tax credit for new solar power systems until the year 2032. Local and state governments and utility companies might also offer rebates, discounts, and dedicated financing plans that could save you more.

Solar System CapacityEstimated Payback period
1 kW1.4 years
2 kW2.7 years
5 kW6.8 years
10 kW13.7 years
